National Synchrotron Light Source II achieves 'first light'The brightest synchrotron light source in the world has delivered its first x-ray beams. The National Synchrotron Light Source II (NSLS-II) at Brookhaven Lab achieved "first light" on October 23, 2014, when operators opened the shutter to begin commissioning the first experimental station (called a beamline), allowing powerful x-rays to travel to a phosphor detector and capture the facility's first photons.http://phys.org/news337334656.html

Conversely, cells that refuse to die when expected can lead to cancer. So scientists interested in fighting cancer have been keenly interested in learning the details of "programmed cell death." They want to understand what happens when this process goes awry and identify new targets for anticancer drugs.http://phys.org/news321299856.html

NanotechnologyWed, 23 Apr 2014 06:41:56 ESTnews317454105Pressure transforms a semiconductor into a new state of matter(Phys.org) —By applying pressure to a semiconductor, researchers have been able to transform a semiconductor into a "topological insulator" (TI), an intriguing state of matter in which a material's interior is insulating but its surfaces or edges are conducting with unique electrical properties. This is the first time that researchers have used pressure to gradually "tune" a material into the TI state; as such, the study gives scientists a new route for discovery as they search for TIs that could be used in advanced electronics applications.http://phys.org/news306055762.html

When light strikes organic compounds bound to certain surfaces, it can split them into atomic and molecular fragments called photoproducts. These fractured pieces offer crucial clues to how and why light breaks some chemical bonds, which is at the core of understanding how solar energy can be used to remove pollutants from the environment. http://phys.org/news303034716.html

The ubiquitous liquid is key to the structure, folding and stability of proteins, but one of the still unanswered questions in the study of the structure and function of proteins and DNA is their exact relationship to their water environment. All of the molecules in our bodies function in water, but until now, we haven't had a lot of experimental techniques to understand what water is doing or where it is binding to the interior surfaces of proteins.http://phys.org/news285581750.html

PhysicsThu, 28 Feb 2013 09:40:01 ESTnews281262349Resolving the internal structure of nanoparticle dimers linked by DNALight and x-ray scattering experiments have revealed the structure of nanoparticle dimers linked by flexible DNA chains. These dimers were basic units in a multi-scale,hierarchical assembly, and served as a model system to understand DNA-mediated interactions, particularly in the non-trivial regime when the nanoparticle and DNA links were comparable in size. We found that the interparticle separation within the dimer was primarily controlled by the number of linking DNA. Researchers summarize their findings in a simple model that captured the interplay of the number of DNA bridges, their length,the curvature of the nanoparticle, and the excluded volume effects. We demonstrated excellent agreement of our analytical model with both our experimental and computational results, without use of free parameters in the model. http://phys.org/news277552521.html
